The results of a study of the influence of slags from various manufacturers on the spreadability, strength and shrinkage of self-compacting fine-grained concrete are presented. It was found that replacing up to 30% of cement with slag reduces the strength of concrete only in the initial period of hardening. It was shown that the use of slag can significantly reduce the shrinkage of concrete.
